Potentiometer Wiring Schematic
How to wire a potentiometer.
Potentiometer wiring schematic. Potentiometers also known as pot are nothing but variable resistors. The terminal 2 is connected to the wiper. Here s what you need to know about choosing the right pots for your guitar. Some guitar wiring circuit designs use 300k or even 1 meg pots.
500k vs 250k tone pots. Potentiometers or pots are a type of resistor used to control the output signal on an electronic device like a guitar amplifier or speaker. In the circuit diagram shown below the terminals of the potentiometer are marked 1 2 and 3. They can provide a variable resistance by simply varying the knob on top of its head.
Between the two side pins of the potentiometer there is a strip of resistive material. For example as carbon. It can be classified based on two main parameters. We call the middle pin the wiper.
Both 250k pots and 500k pots have their place in making a guitar sound great. The voltage supply is connected across terminals 1 and 3 positive lead to terminal one while negative lead to terminal three. It is connected somewhere on the strip between the two ends. Connect end 1 of the potentiometer to the voltage source and attach the wiper terminal 2 to ground.
One is their resistance r ohms itself and the other is its power p watts rating. They have a small shaft on top that functions like a knob. Full size pot shafts usually have fine splines needing 3 8 round mounting holes. It has three pins and the schematic symbol looks like this.
